Gun and ammunition sales have surged over the past several years on fears that Obama would push new control measures. Gun manufacturer profits have risen as well, through a run of mass shootings and the president's continued inability to persuade Congress to agree to any of his proposed gun legislation, such as expanded background checks.
The stock market shows that story. If you'd bought shares of Sturm, Ruger & Co. in 2009, they'd be worth about 10 times as much today. That's a slightly better return than if you'd bought Apple.
